description
The TLV5638 is a dual 12-bit voltage output DAC with a flexible 3-wire serial interface. The serial interface allows
glueless interface to TMS320 and SPI, QSPI, and Microwireserial ports. It is programmed with a 16-bit
serial string containing 4 control and 12 data bits.
The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. The buffer features a Class
AB output stage to improve stability and reduce settling time. The programmable settling time of the DAC allows
the designer to optimize speed vs power dissipation. With its on-chip programmable precision voltage
reference, the TLV5638 simplifies overall system design.
Because of its ability to source up to 1 mA, the reference can also be used as a system reference. Implemented
with a CMOS process, the device is designed for single supply operation from 2.7 V to 5.5 V. It is available in
an 8-pin SOIC package to reduce board space.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: Long term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction
of overall device life. See www.ti.com/ep_quality for additional information on enhanced plastic packaging.

NOTES:
1. Due to the x2 output buffer, a reference input voltage (VDD−0.4 V)/2 causes clipping of the transfer function. The output buffer of
the internal reference must be disabled, if an external reference is used.
2. Long term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction
of overall device life. See www.ti.com/ep_quality for additional information on enhanced plastic packaging.
